A cracked pushrod cup will do the same. My 3 had one when I purchased 
her. I had just about decided to go through the engine when I pulled the 
valve cover and noticed an oil line on the outside of a cup. Turned out 
to be the seam of a crack. The cup opened up under pressure and sounded 
just like a top end rod bearing.
